@pepson ok, so mysgw does at least log to syslog, as seen here

Dec 27 21:12:27 domoticz mysgw: Starting gateway...
Dec 27 21:12:27 domoticz mysgw: Protocol version - 2.2.0-rc.2

but nothing else. I expected there to be more information, but maybe I'm just not familiar enough with the raspberry pi gateway.

[pepson]

Yes but only one time read and then start the problem.

[gohan]

Can you try building the ethernet gateway instead?

[pepson]

Ethernet work ok. But i better want serial and found bug and solution why not working serial...

[gohan]

I just wanted to make sure at least it was working OK as ethernet.

[pepson]

Problem is only on serial...

[pepson]

Please help...

[zboblamont]

@pepson Just a suggestion, but are you sure the Pi3 is looking at ttyUSB1, ie have you confirmed this is the Gateway serial connection ?
I am using direct serial connection to the pi3 GPIO as ttySO with Domoticz, but when I tried a USB Gateway at one point, the connection was NOT working using the expected ttyUSB quoted. I had to check the tty connections via Putty to establish the actual link...

[pepson]

But can you give me commend to build it as you use ttySO ?

[pepson]

I build it as ttySO
./configure --my-transport=rfm69 --my-rfm69-frequency=868 --my-is-rfm69hw --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttySO

and i have and info:

2017-12-28 15:40:21.822 MySensors: Using serial port: /dev/ttyS0
2017-12-28 15:40:21.832 Error: MySensors: Error opening serial port!

[pepson]

Then build as /dev/serial0 and the same problem. This is show in log Domoticz. One read version and port closed.

2017-12-28 15:48:14.418 MySensors: Using serial port: /dev/serial0
2017-12-28 15:48:14.418 MySensors: Gateway Version: 2.2.0-rc.2

2017-12-28 15:48:15.418 MySensors: retrying in 30 seconds...

[mfalkvidd]

@pepson could you post your hardware settings in Domoticz? This is what works for me:

Could you also try building the gateway without rfm69 support, to check if the problem is generic or related to rfm69. Use this:

./configure --my-transport=none --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyUSB42
make && sudo ./bin/mysgw -d

[pepson]

Hello
Thanks for your help. I start from beginning build DOmoticz on my RPi3 with clean latest image. After run in Sudo raspi-config i enable SPI and Serial , then install DOmoticz and now all works OK. Then build Mysensor Gateway and all is ok with no error in Domoticz. Works on /dev/ttyUSB42

[pepson]

But how i can build MySensors Gateway on serial with radio RFM69HW but on old version 2.1.1 ?

[pepson]

And have next problem... i build sketch on version 2.2.0-rc2 but after write to Arduino Mini Pro he is not connected to my Gateway on RPI3.

This is sketch. What is wrong ?

@pepson Try walking in little steps trying each stage rather than running into new walls then expressing surprise at broken nose, no offence intended ;)
Gateway and nodes, same platform, same version..... Otherwise they are speaking Chinese and Swedish hoping for somebody to explain the meaning of fubar...

[pepson]

I use the same version now 2.2.0-rc2 but when i programmed sketch to node it not connection to Gateway... That i want come back to version 2.1.1 gateway but i dont know how ? Or resolved problem Node 2.2.0-rc2 i stay on this.

But when run debug gateway show this:

pi@domoticz:~/MySensors $ sudo ./bin/mysgw -d
mysgw: Starting gateway...
mysgw: Protocol version - 2.2.0-rc.2
mysgw: MCO:BGN:INIT GW,CP=RPNGL---,VER=2.2.0-rc.2

mysgw: TSF:WUR:MS=0
mysgw: TSM:INIT:TSP OK
mysgw: TSM:INIT:GW MODE
mysgw: TSM:READY:ID=0,PAR=0,DIS=0

mysgw: TSM:FAIL:DIS
mysgw: TSF:TDI:TSL
mysgw: TSM:FAIL:RE-INIT

This is sketch 2.2.0-rc2

@pepson Let's try the baby steps I referred to earlier.

The current stable version of MySensors is 2.1. Those using 2.2 tend to be experienced people versed in programming and experimenting and problem solving, hence it is not an official release.... yet you are using it and asking for solutions... Hello ?

I am and have been for the last few months using a Pro-Mini with RFM69 as nodes and gateway using 2.1 attached to a Pi3 running Domoticz.... No problems, but slowly coming to understand most of what I am doing...

I am still on baby steps, I don't mind at all, it works.....

[pepson]

Ok but i dont know how build Gateway on version 2.1.1 because when i do step by step as show on mysensors.org it default build me version gateway 2.2.0-rc2
